How can 21st century technology support ongoing collaborative learning?

These links to collaborative learning tools offer teachers opportunities for sharing and effectively integrating technology into learning experiences. Moodle, for example, connects you with a large and diverse learning community with over 330,000 registered users speaking over 70 languages in over 196 countries. And, via Moodle downloads and build ups, thousands of educational communities and connections -- both local and virtual -- thrive!
